PELLI* 
(Plate XXXI.) 
Havine had the opportunity of dissecting the adults of both the sexes Page 451. 
of Gelada rueppelli, the female of which lived a short time in the 
Society’s Gardens, where it died, I desire to record some points in the 
anatomy of the species which appear to be of interest.

With reference to the male, its general colour is a dark sooty Page 452. 
chocolate-brown. The shoulder, forearm, back of hand, and instep, 
as well as most of the tail, with the exception of its end, are black. 
The palest brown is found on the abdomen, though this is very 
dark. A few white hairs mixed with the brown-black of the tail- 
tuft, give that a lightish tint. The longest hair is that between the 
shoulders, where it reaches as much as eleven inches. This lengthy 
hair extends upwards over the occiput quite forward to the super- 
ciliary ridge, and downwards to the loins, below which it rapidly re- 
duces before the base of the tail is reached. Laterally the long hair 
extends over the shoulders, and less considerably under the arms, 
towards the lateral margins and to the surface below the nude chest- 
space. The hair on the abdomen is about 2°75 inches long, that out- 
side the thighs 4 inches, that on the tail an inch, except the end tuft, 
where it reaches 3°5 inches. 
The characteristic nude chest-space is double in the male, being
